Every week 85-year old Morty Goldberg teaches a new success lesson to young Walter Dill who is deferential and naive. Morty is a retired businessman who drinks heavily, gambles a lot, and has an over-sized libido. He also swears like a sailor. His lessons are often absurdly flawed and comically confusing. Although a friendship develops between the elderly mentor and his young pupil, Walter pays a price again and again for Morty's twisted advice.
